Abstract

Sheared convective boundary layer (SCBL) is a frequently observed boundary layer in nature and industry, with the atmosphere being a common natural case. Due to the combination of interacting turbulent effects in a SCBL, mixing and entrainment is not well understood. In this paper, DNS simulations were performed on a system where stably and unstably stratified shear layers are subjected to the additional effects of an evenly distributed constant heat flux at the bottom boundary. The code used to simulate this system was developed in house, and is implemented using the CUDA programming language for graphical processing units. It implements the incompressible Navier-Stokes equations with the Boussinesq approximation for buoyancy driven flows using a finite difference form of the Semi-Implicit Method for Pressure Linked Equations (SIMPLE).
